| Название | Trilby Media Grav CMS >= 1.7.44, <= 1.7.49.5 Deserialization |
|---|
| Описание | ## Description
`FileCache::doGet()` deserializes cached values with `unserialize(..., ['allowed_classes' => true])`. If cache files are attacker-controlled, this allows object instantiation and enables object-injection primitives.
## Impact
Potential object injection and possible code execution through gadget chains, when cache storage tampering is possible.
## Mitigation
- Avoid object deserialization for cache data; use strict JSON/primitive formats.
- Enforce integrity controls and strict permissions on cache directories.
- If deserialization is required, use a strict class allowlist. |
